WHAT IT DOES

What delete_project_variable does on Gitlab Mcp

AI agents call delete_project_variable to permanently remove resources in Gitlab Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_project_variable is rated Critical

The tool performs an irreversible deletion of project configuration data (CI/CD variables). While not directly affecting source code or causing financial loss, deletion of CI/CD variables can break pipelines, expose secrets if misconfigured, or disrupt deployment processes.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete a CI/CD variable from a project'. This is an irreversible data deletion operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_project_variable safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Gitlab Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_project_variable, this is the rule to start with:

delete_project_variable Hidden

delete_project_variable is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.

The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab Mcp, apply this rule, and every delete_project_variable call is checked against it from then on.
